 ABSTRACT
Crysophylum albidum oil was extracted from its seed. The percentage yield was 2.56%. The characterization of the oil showed showed that the refractive index is 1.487, peroxide value is 45.4mg/kg, iodine value is 50.76g, saponification value is 105.188, free fatty acids 47.46 and acid value is 94.92. The Punched Ager Diffusion Method was used to assay for the antimicrobial and anti fungal properties of the oil in the test isolate. The antimicrobial and anti fungal activity showed some inhibitory effects against test organisms; Staphylococcus aureus, E. coli, B. subfilis, C. albican and A. flavons, but non for S. pyogens. The minimum inhibitory concentration of these test organisms are as follows; Staphylococcus aureus 0.16, E. coli 0.06, B. subfilis 0.14, C. albican 2.50 and A. flavons  0.40.
The pharmacological screening confirmed the medical value of this plant oil and it established a good support for the sample in herbal medicine and as a base for the development of new drugs and phytomedicine.
